The ERZ-E11F102 is a unit of TVS - Varistors, MOVs (Transient Voltage Suppressors - Varistors, Metal Oxide Varistors). It is a combination of a Metal Oxide Varistor (MOV) and an EMI Suppressor in a single package. In this article, we discuss the application field and working principle of the ERZ-E11F102.

Applications of ERZ-E11F102

The ERZ-E11F102 is an ideal protection device for IT equipment, such as game consoles, set top boxes, household electronics, telecommunication systems, modems and fiber-optic applications. It provides protection from transient voltage events caused by lightning, load switching, static discharge, line-to-ground faults and other transient voltage events. It also responds quickly to suppress over-voltage conditions.

It has great surge performance, making it ideal for areas with high rates of lightning strikes or voltage spikes. Its EMI suppressing capabilities reduce the amount of interference that can be emitted from the device, by absorbing the antenna-coupled EMI energy and preventing it from radiating. The ERZ-E11F102 is designed to be robust, and its design makes it capable of withstanding harsh environmental conditions for reliable operation in the field.

Working Principle of ERZ-E11F102

The ERZ-E11F102 uses a combination of a Metal Oxide Varistor (MOV) and an EMI Suppressor. The MOV contains a zinc oxide resistor material that is sensitive to changes in voltage. When a voltage reaches the triggering voltage (or breakdown voltage) of the MOV, it begins to conduct or acts as a short circuit, allowing current to flow freely. This “short” causes the voltage to drop quickly and limits the current to a safe level.

The EMI Suppressor in the ERZ-E11F102 acts as a filter for high frequency emissions and harmonics. It is designed with a high-frequency bypass to help reduce the amount of interference that is radiated. By providing a low impedance path for the EMI currents, the EMI Suppressor enables the EMI energy to be dissipated without the signal reaching the end device.

The ERZ-E11F102 also includes a transient voltage spike limiter, which will allow voltage in excess of the breakdown voltage to be limited. This limiter is designed to help protect circuits from the destructive effects of over-voltage spikes.

Conclusion

The ERZ-E11F102 is an excellent protection device for IT equipment, providing protection from transient voltage events caused by lightning, load switching, static discharge, line-to-ground faults and other transient voltage events. In addition, it provides EMI suppression and transient voltage spike protection to help protect sensitive circuits. Its robust design and high surge performance make it suitable for harsh environmental conditions in the field.
